'GAIRBAGE REFUSE INCINERA'IOR.

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed April-1 5, 1912. Serial No. 690,977.

The main objects of this invention are to dispose of garbage and refuse such as paper, bottles, tin cans, etc. in apartment buildings,

flats, hospitals, residences, and the like, in a convenient andsanitary manner; to utilize for this purpose chimneyspr chimney flues with which such buildings are ordinarily provided; and generally to improve the con struction and operation of devices of this class.

It consists in the peculiar construction, arrangement and combination of parts as hereinafter particularly described and defined in the claims.

In the accompanying drawing like characters designate the same parts in tlie several figures.

Figure 1 is a vertical section on the line 1-1 refu e incinerator embodying the invention as designed more particularly for apartment buildings and the like; Fig. 2 is a vertical section of the ame on the line 2-2, Fig. 1, in a plane at right angles to the plane of Fig. 1; Fig. 3 is a section on the line 3-3, Fig. 4, of a modified form of the incinerator as designed more particularly for single dwellings or comparatively small buildings; and Fig. 4 is a section on the line l-4, Fig. 3.

Referring to Figs. 1 and 2-, the incinerator comprises a chimney or chimney flue a, such as apartment buildings, flats and the like are ordinarily provided with. It is open at the upper end to the atmosphere, and serves in the usual way as, a smoke or ventilating flue for gas or other heating apparab and a furnace or heater 0 being shown in Fig. 1. At its lower end of the chimney or flue a is enlarged and" I arranged to form and serve as a garbage and refuse cremating or burning chamberchwhich has an overhanging wall at its top to one side of the flue a leading therefrom, and which like the chimney flue a, may be constructed of brick as shown, or of other suitable material. The lower part of the incinerator or Fig. 2, of one form of garbage and eated, as shown, in the cellar or basement of the building, and is provided with self-closing fire, draft and ash doors 6, f and g, at the front or one side. It is also provided with a grate k, which extends rearwardly and upwardly from a line between the doors f and g to a higher level at or adjacent to the rear or opposite wall of the chamber.

The grate may be conveniently constructed as shown, of flat metal bars arranged edgewise and parallel with one another. and supported at the ends on cross bars or plates 2', or upon ledges extending inwardly from opposite walls of the chamber d. The grate bars are connected and held in place relative to one another by rods 9' passing transversely through them, and by interposed spacing washers on the rods. The grate bars may be bent and set at an inclination as shown in Fig.1, or they may be formed andjset with their lower portions substantially. horizontal and their rear and up er portions substantially vertical or paral el with and at a distance from the rear wall of the chamber d, as shown in Fig. 3. seemstructed and arranged, the rate constitutes a receptacle adapted to receive and hold an accumulation of garbage or refuse dropping through the chimney flue a, and at the same time afford an upward draft or a passage for air from the ash pit or lower part of the chamber d into the upper part thereof, and thence into the chimney fine a by way of the by-pass beneath the overhanging wall formed by spacing the refuse containing receptacle from the wall of the cremating chamber at points under the overhanging wall at the top of the chamber, which will cause the air currents to be directed access the refuse material in the receptacle and whereby garbage or Wet refuse is dried preparatory to burning it.

The chimney or flue a is provided with an inwardly enlarging and downwardly inclined chute 7c, the upper and outer end of which is inclined and provided with a selfclosing' door I, as shown in- Fig. 1. The stoves, ranges or heaters connected with the chimney flue' a, and especially the heater 0 in the basement of the building, tend to heat or warm the air in the incinerator and to produce and maintain an upward draft through the grate h and the garbage and other refuse thereon, the stoves or ranges above the basement being connected by venthe cremating chamber 01 is preferably 10- a the door 6 or f and tilating or smoke pipes m directly with said flue, and the heater 0 being connected "with the chamber (Z below the grate by a pipe 01. Other means may however, be provided for producing and maintaining a draft of air through the incinerator for drying the garbage deposited therein, for example, a steam coil 0, or a gas burner 21, as shown. A branch pipe 9 provided wlth a damper r connects the heater 0 or pipe n with the upper part of the chamber (Z, to afford, when desired, a direct draft connection between said heater and the flue a.

In the operation of the incinerator, garbage and refuse such as paper, bottles, tin cans, etc, are thrown into the fine a through the doors Z, and fall upon the grate h, where they accumulate and are subjected to the drying effect of the upward current of air through the grate resulting from the use of the stoves, ranges and heating apparatus connected with the chimney flue a or chamber Z, or produced by means specially provided therefor, such as the steam coil 0 or gas burner 7). v

Bottles, cans and other incombustible-articles thrown into the furnace with garbage and other refuse, tend to keep the material deposited upon the grate in a loose and ventilated condition, so that the air'draft will more readily pass through o1' 1)enetrate and dry the same. From time to time, according to the quantity of garbage and refuse accumulated on the grate, it is lighted through burned, any or all of the doors a, f and g, or the dampers therein, being opened to supply air for combustion.

The soot produced and deposited on the walls of the line a by the burning of the garbage and refuse in the chamber .0? and also by the stoves and heaters connected with said flue, prevents garbage from adhering thereto, while the garbage and other refuse thrown into and falling through the flue, removes surplus soot therefrom. The soot falling on the garbage as it accumulates on the grate in chamber 03, retards decomposition, and tends to prevent offensive odors generating in the incinerator.

The burning of the combustible portions of the garbage and refuse thoroughly sterilizes and disinfects the walls ofthe fine a incombustible refuse, such as bottles, cans, etc. The incombustible resldue, such as bottles, cans and ashes, which remains after the garbage and refuse is burned, is removed from the grate and the ash pit below, through the doors f and g.

The flue a is made enough larger than the opening into the chutes la and the draft opening into the chamber d, to prevent the escape of smoke and gases or odors from the incinerator into the building when the doors Z are opened.

' by a lateral Referring to Figs. 3 and 4, showing a modified construction of the incinerator, the

d than shown in Figs. 1 and 2, to afford a larger ash pit for the accumulation of ashes and the incombustible residue of garbage and refuse and thereby obviate the necessity of removing them so often. The grate is made in sections, the lower part being substantially horizontal and composed of one or more rocking sections 8, and the upper part being substantially vertical or parallel with the rear wall of chamber a? and composed of one or more sections t, suspended on a cross rod 16, so as to maintain a passage for air from the lower into the upper part of said chamber when there is an a'ccummulation of garbage on the grate.

.For dumping the grate, the rocking seewith a lever arm or handle '0 located outside of the chamber cl where it is conveniently accessible. This form of the incinerator is shown as having but one fire and draft door f above the grate, but if desired, it may be provided with more, The operation of the apparatus shown in Figs. 3 and 4 is the same as that shown in Figs. 1 and 2, except that incombustible refuse too coarse or large to pass between the grate bars is dumped after burning into the ash pit and removed through the door 9, instead of through the door f above the grate, as in the form Figs. 1 and 2.

Various modifications other than those specifically mentioned may be made in the construction and arrangement of parts of the incinerator to adapt it to buildings of various kinds and to various conditions, without materially affecting its principle and mode of operation and without departure from the scope of the invention.
